Answer:
The interest is $10.39.
Step-by-step explanation:
Your original purchase price was $950.00 plus 5% sales tax.
Purchase price = [tex]950+0.05\times950=997.50[/tex] dollars
Monthly Rate = [tex]12.5/12/100=0.010417[/tex]
So, interest on the purchase price = [tex]997.50\times0.010417[/tex]
= $10.39
Hence, the interest is $10.39.
